Green Tea,
Glycine May Slow Tumor Growth - WebMD, 11/2/01 -
"high levels of glycine reduced breast tumor growth
rates by 15% in rats by blocking the growth of new tumor-feeding blood
vessels. The special diet also reduced wound-healing by 30% ... Tumors and
wounds have one very important thing in common -- they both produce new
blood vessels through the same mechanism, known as angiogenesis ... If you
can block one response, you can block the other"

Improved
Cardiovascular Function in Old Mice after N-Acetyl Cysteine and Glycine
Supplemented Diet: Inflammation and Mitochondrial Factors - J Gerontol A
Biol Sci Med Sci. 2018 Mar 10 - "Metabolic, inflammatory and functional changes
occur in cardiovascular aging which may stem from oxidative stress and be
remediable with antioxidants. Glutathione, an intracellular antioxidant,
declines with aging, and supplementation with glutathione precursors, N-Acetyl Cysteine (NAC) and Glycine (Gly), increases tissue glutathione. Thirty month-old
mice were fed diets supplemented with NAC or NAC+Gly and, after seven weeks,
cardiac function and molecular studies were performed.The NAC+Gly
supplementation improved diastolic function, increasing peak early filling
velocity, and reducing relaxation time, left atrial volume, and left ventricle
end diastolic pressure. By contrast, cardiac function did not improve with NAC
alone. Both diet supplementations decreased cardiac levels of inflammatory
mediators; only NAC+Gly reduced leukocyte infiltration. Several mitochondrial
genes reduced with aging were upregulated in hearts by NAC+Gly diet
supplementation. These Krebs cycle and oxidative phosphorylation enzymes,
suggesting improved mitochondrial function, and permeabilized cardiac fibers
from NAC+Gly fed mice produced ATP from carbohydrate and fatty acid sources,
whereas fibers from control old mice were less able to utilize fatty acids"

Dietary
glycine and blood pressure: the International Study on Macro/Micronutrients and
Blood Pressure - Am J Clin Nutr. 2013 May 8 - "The
study was a cross-sectional epidemiologic study that involved 4680 persons aged
40-59 y from 17 random population samples in the People's Republic of China,
Japan, the United Kingdom, and the United States ... glycine, but not alanine,
was significantly related to BP. Estimated average BP differences associated
with a 2-SD higher glycine intake (0.71 g/24 h) were 2.0-3.0-mm Hg systolic BP
(z = 2.97-4.32) stronger in Western than in East Asian participants. In
Westerners, meat was the main dietary source of glycine but not in East Asians
(Chinese: grains/flour and rice/noodles; Japanese: fish/shellfish and
rice/noodles)"
